Increase default pipe buffer size on VMS to 8192 on 64-bit systems.

As Charles Lane's piping code reaches its 10-year anniversary, it's
time to bump up the default to something slightly more appropriate
for modern systems.  In addition to other benefits, this fixes test
failures when a test script outputs a large amount of text on one
line (e.g., t/re/reg_posixcc.t).
